RESUMEN
OBJECTIVE: To investigate the effect of silent information regulator 1 (SIRT1) gene polymorphisms on ambulatory blood pressure in hypertensive patients. METHODS: Three hundred forty hypertensive patients were recruited from January 2013 to January 2015. SIRT1 Tag single-nucleotide polymorphisms (SNPs; rs2273773, rs4746720, and rs7896005) were genotyped using a PCR-direct sequencing method, and the association between the SIRT1 gene SNPs and ambulatory blood pressure was analyzed. RESULTS: After adjusting for confounding factors, patients with the rs2273773/CT+CC genotypes had lower 24-h systolic and diastolic blood pressures; there were no associations between rs4746720 and rs7896005 genotypes and blood pressure. CONCLUSION: The SIRT1 gene polymorphism (rs2273773) is significantly associated with ambulatory blood pressure level in Han Chinese patients with hypertension.
